大家好，之前由于 Android 端 App 把系统内核用 X5 浏览器内核替换，导致我无法切换 context 同时 Appium 无法查看 web 页元素，根据论坛上大神的方法配置了后，还是不行，大家有遇到过这种问题吗，怎么解决的？

配置

• Appium version:v1.6.4
• Appium inspector:1.1.0-beta.1

• System version:4.4.4

  def setUp(self):
  
      desired_caps = {}
      desired_caps['platformName'] = constants.Android_Platform_Name
      desired_caps['platformVersion'] = constants.Andriod_Platfrom_Version
      desired_caps['deviceName'] = constants.Andriod_Device_Name
      desired_caps['unicodeKeyboard'] = "True"
      desired_caps["resetKeyboard"] = "True"
      desired_caps["noReset"] = "True"
      desired_caps["chromeOptions"] = {'androidProcess':'com.tencent.smtt:tools'}
      desired_caps['app'] = PATH(
         constants.Apk_Dir
      )
  
      self.driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
  

  错误 log
